PLOW-WHEEL.

SPECIFICATION forming part of Letters Patent No. 273,779, dated March13, 1883,

Application tiled July 1, 1882.

.To all whom it may concern Be it known that I, ERNEST E. S\VAN,acitizen of the United States, residing at Texas, county of Kalamazoo,State of Michigan, have invented a new and useful Plow-lVheel, of whichthe following is a specification.

My invention relates to the wheel of a plow and its standard forconnecting it with the plow-beam.

It has for its object a construction whereby the bearings of the wheelare protected from sand and dirt and the wheel is proof againstwabbling. Another object is to so construct the upper portion of thewheel-standard that it may be readily connected with any style ofplow-beam in use in a manner that it can be adjusted both vertically andlaterally, in accordance with the desired depth of plowing and thenumber of horses used, substantially in the manner explained in thedetailed description.

In the drawings forming a part of this specification, Figurel is a sideelevation of the device attached to aplow-beam; Fig. 2, top view withbeam broken away; Fig.3,section on line 1 2 in Fig. 1, showing theinternal construction of the wheel and the form of the axle not insection; Fig. 4, section on line 3 4 in Fig. 1; and Fig. 5, lower end ofthe wheel-standard, showing the plan of the internal formation whichreceives the wheel-axle.

A I) are the forward and rear arms of the wheel-standard, the sameconverging toward the lower end, where they are united.

f is a curved serrated upward extension of arm A, and 3 is a curvedserrated lateral extension of arm D. These parts are held secured tobeam B by bolts t r in the manner shown in Figs. 1, 2, and 4. Said boltsare formed with eye ends, through which the extensionsfg are revolublylocated, said eye ends being located in a serration ot said extensions.

z z are washers having recesses in which the extensions f y are located.By loosening bolt t, owing to the curve of arm A and the revolublecapacity of extension y under beam B, the standard and wheel may beswung up or down; and by loosening bolt 1', owing to the curve ofextension 3 and the revoluble capacity of arm A on the side of beam B,the

(N0 model.)

standard may be swung laterally, as in Fig. 2, setting the wheel at anoblique angle with the line of the floor-beam. This is done when usingthree horses, as the plow-beam is then drawn to one side, which stillkeeps the wheel on a line with the line of draft. It will be observedthat the holes in which bolts 1? r are located can be readily made inany plow-beam and the wheel-standard easily attached.

F is the wheel, provided with a pocket, 8, at its center, which receivesthe front end of axle r r. Said axle has a center extension or circularflange, c, which fits against the open end of pocket 8, preventing thewheel F from working farther onto the axle r r.

a is a cap, the rim of which is bolted to wheel F, the crown being boredto receive the inner end of axle r1. This cap prevents the wheel fromrunning oft from the axle. A groove, m, is formed around the cap at thebase of the rim, the use of which is hereinafter explained. The axle r1" has a center hole lengthwise through it, in which bolt 6, having head6, is located. The inner end, it, of the axle is formed angular orsquare and adapted to tit into recess h of the standard. The lower endof said standard, Fig. 5, has an extension, E, having a recess, in whichcap a is located, said recess having a rearward extension, 0, receivingthe other end of the axle r T. The end of said recess a is formed squareat h for the reason above stated, which prevents the axle r 1' fromturning. The axle r r is firmly secured in place by tightening up thenut ot'bolt e, which tightening can in no way bind the wheel F. a. is aslot formed through extension E, as an outlet to any sand or dirt whichmight workits way in the larger recess of said extension past groove in,said groove being designed to prevent any sand working past it. 'By thisarrangement it is impossible for any sand to get in the wheel-bearings.

The device may be lubricated by removing stopperacand turning the plowon its side. Thus no dirt becomes mixed with the oil, and, owing to thepeculiar construction, the oil is long retained.

Having thus described my invention, what I claim is- 1. The combination,with the standard, re-

cessed as described, of the hollow axle having round, curved. serratedextension and the latthe circular flange and square end, the wheel eralround, curved, serrated extension,all sub- 10 having the pocket and theattached cap, and stantially as set forth. the fastening bolt and notall substantially as 5 described.
